Earlier I have installed ubuntu live image using above two mentioned utilities, numerous times. But, on a 2gb kingston flash-drive.

Today, i am trying to install the live-image on 4gb HP flash-drive. Both the utilities install, i can see the files in the drive, even the wubi-installer is working, it say press "reboot" to boot in live-ubuntu. But, when i press "reboot" it does not reboot my win7.

Now, when i reboot, select boot-usb in bios, it say "no boot record". I am making my usb bootable, using the utility, even then nothing is working out. Did this a few times.

Is 4GB usb a prob, does anyone knows how to partition my usb in 2-2gb and install it on one partition, and then use the live image. Is it possible.
